Package com.apple.foundationdb.linear.simd

package com.apple.foundationdb.linear.simd
SIMD-using implementations of vector primitives, depending on the jdk.incubator.vector incubator module.

Isolation invariant: this package is the only place in the codebase that imports jdk.incubator.vector.*. The classes here are loaded reflectively by RealVectorPrimitives.selectBackend() so the rest of the module can be compiled and run without the incubator module being available on the JVM. If the module is missing at runtime, loading SimdBackend throws NoClassDefFoundError and the dispatcher falls back to the scalar implementation in the parent package.

Build configuration must pass --add-modules jdk.incubator.vector to the compileJava task that compiles this package. To exercise the SIMD path at runtime, the same flag must be passed to the JVM.
